Abstract: A composition includes: a compound including an aromatic ring; and a first polymer including a first structural unit represented by formula (1) and a second structural unit represented by formula (2). A content of the first polymer with respect to 100 parts by mass of the compound is no less than 0.1 parts by mass and no greater than 200 parts by mass. R1 represents a hydrogen atom or a substituted or unsubstituted monovalent hydrocarbon group; and R2 represents a substituted or unsubstituted monovalent hydrocarbon group. R3 represents a hydrogen atom or a substituted or unsubstituted monovalent hydrocarbon group; L represents a single bond or a divalent linking group; Ar represents a group obtained by removing (n+1) hydrogen atoms from a substituted or unsubstituted aromatic ring; R4 represents a hydroxy group or a monovalent hydroxyalkyl group; and n is an integer of 1 to 8.
